Members

Member	Description
aac_type	AAC encoding and decoding protocol type. Currently, only HI_AAC_TYPE_AACLC is supported.
bit_rate	AAC encoding and decoding protocol bit rate. Currently, as only 48 kHz sampling rate is supported, the supported bit rate ranges from 48 kbit/s to 256 kbit/s in mono channel mode.
sample_rate	Sampling rate. Currently, only 48 kHz is supported.
bit_width	Bit width. Currently, only 16 bits are supported.
snd_mode	Sound channel. Currently, only the mono channel is supported.
transport_type	Transmission encapsulation type of AAC encoding and decoding protocols. Currently, only the HI_AAC_TRANSPORT_TYPE_ADTS type is supported.
band_width	Frequency range. The value can be 0 or in the range [1000, 24000].
